The sync file support in Linux has been stabilized and the new config is
called CONFIG_SYNC_FILE. Even if maybe not so intended, both the
stabilized version and the legacy CONFIG_SYNC can coexist; to begin with
supporting the stabilized version, add CONFIG_NVGPU_SYNCFD_ANDROID and
CONFIG_NVGPU_SYNCFD_NONE as choice configs of which one will be set. A
later patch will extend this with a choice for CONFIG_SYNC_FILE.

Configure the NVLIPT and IOCTRL interrupt registers to rollup
the MIF and TLC errors on the link-specific fatal line and the
DLPL interrupts on link-specific intr_a(fatal) line. Both
link_err_fatal and link_intr_a are rolled up to stall interrupt line.
In the handling ISR, clear the interrupt status registers and print
an error.
Move the interrupt handling HAL code to /common/hal.

Refactor user managed syncpoints out of the channel sync infrastructure
that deals with jobs submitted via the kernel api. The user syncpt only
needs to expose the id and gpu address of the reserved syncpoint. None
of the rest (fences, priv cmdbufs) is needed for that, so it hasn't been
ideal to couple with the user-allocated syncpts.
With user syncpts now provided by channel_user_syncpt, remove the
user_managed flag from the kernel sync api.
This allows moving all the kernel submit sync code to be conditionally
compiled in only when needed, and separates the user sync functionality
in a more clear way from the rest with a minimal API.

syncpt with nvhost config) from

PMU IRQs were not enabled assuming entire functionality for LS PMU.
Debugging early init issues of PMU falcon ECC errors triggered
during nvgpu power-on will be cumbersome if interrupts are not
enabled early. FMEA analysis of the nvgpu init path also
requires this interrupt be enabled earlier.
Hence, Enable the PMU ECC IRQ early during nvgpu_finalize_poweron.
pmu_enable_irq is updated to enable interrupts differently for
safety and non-safety. PMU interrupts disabling is moved out
of nvgpu_pmu_destroy to nvgpu_prepare_poweroff. Prepared new
wrapper API nvgpu_pmu_enable_irq.
PMU ECC init and isr mutex init is moved to the beginning of
nvgpu_pmu_early_init as for safety, ls pmu code path is
disabled. Fixed the pmu_early_init dependent and mc
interrupt related unit tests.
Update the doxygen for changed functions.
